Dreaming of mother

Asalaamu Alaikummy mother passed away in March 2012 due to an illness. She had breast cancer which then spread to her liver. She was 50 yrs of age.She was intending on making umrah just before she got sick but my dad was schedule to go for a bypass so that did not materialize.Following the night of her passing away, a family friend had a dreamt in which my mum was wearing white ; said Please tell my husband that I am ok and he shouldnt worry about me. I am sitting in front of the rodha mubarakMy sister also had a dream a few days later that my mum was telling her about her death.She said her death was easy and we, her daughters, must not be afraid of death ; she knew exactly who was at her funeral and who buried her.How do we interpret these 2 dreams?Also Muftie sahib, please can you tell me what is best to read for esaale sawaab onto her.Shukran
